TO ALL WHOM IT MAY CONCERN-z Be it known that 1, WILLIAM P. YEOMAN, of 'W'aukegan, in the county of Lakejn the State of Illinois, have inventeda useful Improvement in Machines for Edging Wall-Paper; and I do hereby declare that thofollowing is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of' this specification, in which- Figure 1 is a perspective representation of my invention. Figure 2 a. sectional representation of the rollers, and the knife-attachments.

The nature of my'invention consists inthe use of rollers covered with cloth. or other similar material, and arranged with circular concave knives, and a spring for keeping them in'position for trimming the edges of wallpaper, and for other similar purposes, and in an adjustable table for supporting and guiding the paper. through between the rollers, whereby any width of'marginmay be trimmed ed. The means now used for this purpose ere'the' common shears, which involve a great amount of diflicult labor, which, when done, does not l'esult in leaving the edge of the paper as true as when out by a machine. I p

I propose to obviate the diificulties heretofore experienced in cutting paper, by constructing a machine whichshcll be cheap, compact, and durable, and so simple thatpaper-han'gers can use it without-any particular I instructiomand perform a given amount of labor in one-eighth ofthe time new consumed In-order to give a correct understanding of my invention, I have marked corresponding parts with similar letters, and will noi' give a detailed description. A represents a ubstantial woodenbed-piece, to which a track G H, and standards 13 B, are rigidly attached. These standards are held together at their tops-by means of a cross-piece, C, secured to them by screws or bolts Z Z, fig. '1, and have holes. made horizontally through them for supporting the journals X X of the rollers J K. Fig. Irepresents the rollers, with the cloth or covering removed in order to show. the knives S S more clearly, hut-fig. 2 shows the cloth, and the construction of the rollers, which aremade of hard wood, and in two parts each, the shanks '.l..'.l. being turned down to suit the eyes'of the knives S S, and to receive rings'N (5, used to fill out the length of the -rollers, after said knives are properly secured, in orderthat the margin cut-from the paper may be drawn through with the main sheet. m m, fig. 2, represent cloth which is used to cover the rollers, and thus provides a convenient elastic surface for movingthe paper between the knives without tearing it. Any other elastic material may, however, be used which will adhere to the rollers, but I considercloth the cheapest, and fully answering the purpose. The knives S S should be made of good steel, and concaved on their opposing faces, in order that their edges may work closely together at the point where they overlap each other. The shape of the knives is clearly shown at fig. 2, as is also the screws 2: which hold them to the ends of rollers J K. P represents a. common coil-spring wound around the shank of. the upper roller, and is made to bear against the ring N, and thus keep the face of the upper knife against the lower one, this being an important arrangement for keeping the knivesin position for cutting thin paper. A table, D, having cleats I for holding it on the track G H, is arranged to slide back and forth parallel with the roller J K, and regulate the width of the strip to he cut oil', and also has a stationary guide, F, and a movable guide, E, the latter being arranged with pins soas to be set to any width of paper. l

' 7 Operation. The wall-paper should be hung in the roll, on a rod, Y, resting in hooks d,after which the end of the paper can be put between the rollers J K, and the crank'R, attached to the journal of the lower roller, turned slowly around until the margin is cut oil, or the paper has all passed through the machine.

'Having thus, fully described my invention, what I claim,-'and desire to secure by Letters Patent, is-- 1. The combination of rollers .l K, spring 1, knives S S, cloth mm, and rings N O, substantially as and for the purpose set forth. I I

2. The combination of the table D with rollers 'J K, substantially as herein specified.
